there are 2 hoses one is smaller than the other one goes to the htr cntl valve but the other i don't know
that's why i would like to see a diagram
If you are talking about the two vacuum lines that go through the firewall to the engine compartment, one go to the heater control valve to turn the water flow on and off, the other goes to a main vacuum port on the intake of the engine, many of them have a small one way valve in it also.
